Anna is two years younger than Elsa, and Elsa is two years younger than Kristoff. If the sum of their current ages is 81, then what would thier ages after three years.

26, 28, and 30

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

pretty sure 750 each month!
